VAPO R-STOVE.

SPECIFICATION forming part of Letters Patent N o. 483,051, dated September 20, 1892. Application tiled January 9,1890. Serial No. 336.397. (No model.)

To all whom it may concern:

Be it known that I, RUDOLPH FLICK, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Vapor-Stoves; and I do hereby declare lthat the following is a full, clear, and exact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same.

My invention relates to improvements in vapor-burners; and the object of the invention is to provide a burner with means whereby the burner may be provided with combustible vapor or gas and promptly lighted Without other preliminary labor or attention.

Heretofore in starting a vapor burner or stove at least one burner in the group of two or more had to be initially started by turning a quantity of oil into a drip-cup or its equivalent beneath or about the burner and then lighting the oil and generating a heat which Would put the burner into a Vaporizing Condition. If the stove were an individual-burner stove, this process had to be gone through with each burner in turn before it could be used, unless, as in some cases, a heating-tube were provided from a burner that was lighted. In case the stove were what is known as a single generator,J the generating-burner Would be thus initially started and gas or vapor for the side burners would be provided from the Central generator-burner. These represent the common Ways by which initial starting of a burner was effected. Other Ways and means have been tried, but not generally with success or satisfaction, and the practical methods heretofore known and employed of starting a burner Inay be said to be covered by the foregoing statement.

My invention is designed to Overcome the Objections to the drip-cup and to avoid the complications and numerous valve and other attachments necessary in connection with heating and lighting tubes Which are designed in part to replace the original method of initial starting, and this is accomplished by providing a tube with a valve and mechanism whereby the fluid is fed into a supplytube and converted immediately into a vapor whiohsupplies combustion.

My invention is further designed to preconstruction, arrangement, and combination efr of parts substantially as shown and described, and particularly pointed out in the claims.

In the drawings, Figure l is an end elevation of a stove provided with myinvention, a part of which is broken in sections to more clearly disclose the construction. Fig. 2 is a vertical central sectional view, enlarged, of the valve and spraying mechanism. Fig. 3 is a cross-section of the valve-tube, taken on line a: .'r, Fig. 2.`

A represents a stove-frame, which may beh of any well-known style or form, and B is the burner. This element of the invention also may be of any common and well-known kind.

As shown in Fig. l, the burner is provided with a cap b, suitably perforated, slotted, or the like, as burners usually are, for the escape of the vapor, which cap rests upon a ledge on the inside of the upturned end of the lower branch of the pipe O. The pipe C, as here shown, extends,ordinarily, from near the outside of the base of the burner back horizontally and thence up vertically some distance above the plane of the burner and has placed in its upper end a fluid-supply tube, as shown, to be particularly referred to hereinafter, the Carbureted air being fed to the burner through the pipe C by gravity.

In cold weather the carbureted air in the vapor-tube condenses very considerably and in cold climates to such a degree as at times to render the stove virtually inoperative. For the purpose of preventing condensation in burners of the character herein described, I connect at the upper end of the vapor-pipe an auxiliary device comprising a hot-air pipe O', which forms at the point of connection a U- shaped bend, asshown. yHot air is conducted through this pipe C to the pointof evaporation from the burner, as will hereinafter appear, and prevents condensation of the carbureted air, and at the same time assists vaporization. Of course the particular form of bend herein IOO illustrated need not be exactly followed; but

the lower end of pipe C extends at one side,

and where the two parts are firmly soldered or otherwise secured together. The deiiector D is secured to the un'der side ofthe top plate of the stove by braces d, but may be xed in position by any other suitable means. The shape or form of the deiiector may of course be varied from that shown,if desired,`

without aecting its efficiency. From the point d the deflector ilares downwardly upon all sides forsome distance, so as to be the means of gathering and concentrating a con siderable volume of hot fresh air tosupply combustion as well as to feed a steady volume of air to and through the pipe C', there-y by` assisting or increasing the carburetin g effeet or process.

It is my design to so place the mouth c of the pipe C with respect to the burner and in the deiiector and preventing condensation ofthe carbureted air in the vapor'pipe that when the burner is heated the air which enters the pipe G will likewise be more or less `heated, and thus contribute to vaporization of the injected fluid and prevent condensation ofthe carbureted air in the vapor-pipe regardless of the temperature of the atmosphere in which the stove is operated.

E, Fig. 1, `represents an oil-tank. A supply-pipe e leads from the tank to the valvetube F. (Shown more clearly in Fig. 3.) This valve-tube, preferably, is provided with a neck f, having three several small channels f for the passage of the fluid, and in thebottom of which is a cavity f2, forming a socket or seat for the ball-valve G. A 'stem g and handle g serve to control this valve. The valve, as will be seen, enters the top of bend of the pipe C in such position as to inject the fluid down into the vaporconducting pipe C, so that the vapor will not settle into the branch c2, and thereby cause dashing back from the burner. Ordinarily the valve G, suitably constructed and controlled with the oil under suitable pressure, will be suiiicient in itself to atomize and breakup the oil in such small particles that its vaporization will immediately follow, and of course as this occurs the temperature will be materially lowered and the vapor by its own gravity, and under the conditions pertaining to it will sink down in the branch c2 of the pipe C and appear at -the mouth of said pipe ready for combustion.

This settling down and movement of the vapor of course establishes a circulation in the pipe C, which circulation contributes to vaporization, the result I am seeking. Then Vit would be cold.

when the ,vapor is ignited and the' burner started the draft or circulation through pipe C of course is materially increased, and as the burner-is heated the air which enters the pipe C also is heated in consequence, andthe cir- `culation not only becomes more rapid, but much more eiectual in the vaporization of the oil, as the heat of the air passing through the pipe materially contributes to accomplish this result. Thus with the mechanism provided for spraying and atomizing the fluid, assisted by the hot air from about the burner, I readily vaporize all the fluid that is necessary'for axy and! all` purposes of the burner, and the action is continuous, uniform, and highly satisfactory as long as used. By this construction I not only add a volume of heated air to mingle the air and vapor together 1n the feedtube, but the burner 1s provided with airf in a heated condition, which is gathered and con-"i centrated by the deflector D and fed to the burner jets or openings about its side through.

' d2. Of course vapor will the narrow opening n combine with airmuch more readilywhen the air is heated than when cold, and hence the advantage of taking the supply of air fromabout the burner rather than elsewhere, where To facilitate the process of atomizing and vaporizing of the fluid,

and 2, I insert a spiral wire brush H in the down section c of the pipe immediately heneath the supply-valve. As the oil is sprayed from the valve, particles that are not other# wise broken up will gather upon th1s wlre brush and, being exposed to the draft and the heat through the pipe C', are speedily taken up and converted into vapor and carried away,

ras before described.

Ido not, of course, limit myself to any special construction of atomizing or spraying mechanism, as this may be materially varied and still accomplish the result I seek.

The novelty of the invention comprises, broadly, a spraying, atomizing, or vaporizing construction located and inclosed and serving the purpose herein described, in connection with a supply and commingling hot-air tube.

During evaporation of the oil the air is cooled and the temperature reduced, so that if cold air be used there is a tendency for the air to condense and deposit its moisture,which prevents thorough commingling of air and vapor; but by using hot air the opposite effect is obtained, and the heat produces or causes rapid vaporization `and admixture or commingling of the air and vapor or gas.

In Fig. 2 the mechanism is much enlarged, so as to more clearly show the construction. The valve, for example, in practical use is not much larger than a pin-head, and the slight grooves or channels f incline in converging lines toward the valve-seat and point of discharge.

It will be understood that the oil or iuid the burner isl as shown in Figs. 1i
